Keller Laboratories

Keller Laboratories, commonly referred to as Keller Dental Lab and now operating as NDX Keller, is a full-service dental laboratory focused on restorative and prosthetic dentistry. The company manufactures and supplies dental crowns, bridges, dentures, partials, implant restorations, aligners, and related oral appliances for dentists and dental practices. Keller has also adopted digital dentistry workflows, including CAD/CAM, 3D printing, digital impressions, and model-less crown and bridge fabrication. Founded in 1948 in the St. Louis area, the business is now part of National Dentex, one of the largest dental laboratory networks in North America. Its business is healthcare-related, but it is not a biotech or therapeutic drug developer; it is a commercial dental lab and device/services provider.
